   A New Technique of Torque Ripple Reduction in Saliency-Based Sensorless Drive IPM Motors for General Industrial Applications
By Yoshiaki KANO, Takashi KOSAKA, Nobuyuki MATSUI, Toshihito NAKANISHI [View]
[Download]

Abstract: A new technique is proposed to reduce the torque-ripple of the concentrated-winding interior permanent magnet motor (IPMSM) under saliency-based sensorless drive. It is based on the combination of circular-flux-barriers at the rotor-yoke and the V-shape-magnets. It is applied to 45Nm-5.5kW industrial drive IPMSM to fulfill the torque-ripple requirement with a large region for sensorless rotor position detection.

   Speed-Sensorless Induction Motor Control with Torque Compensation
By Cristiane CAUDURO GASTALDINI, Hilton AbÃlio GRÃœNDLING [View]
[Download]

Abstract: This paper addresses the problem of controlling a three-phase induction motor without speed measurements and with torque compensation. A nonlinear feedback linearization control was designed for a fifth order induction motor model including electrical and mechanical dynamics. The proposed control scheme, which is an indirect field oriented control technique (IFOC) based on feedback linearization control (FLC), is made up of flux-speed controllers. In order to provide an estimated rotor speed for the control system, a model reference adaptive system (MRAS) algorithm based on reactive power was applied. This estimation passes through a Kalman filter, which is also used for the torque estimation. Some experimental results with TMS 320F2812 DSP are provided to verify the proposed system performance in a low speed over load variation conditions.

   Switching strategies for DTC on asymmetric converters
By JosÃ© RESTREPO, JosÃ© Manuel ALLER, VÃctor GUZMAN, MarÃa Isabel GIMENEZ, Julio VIOLA [View]
[Download]

Abstract: In this work the application of additional switching states for the asymmetric converter is studied for its use in direct torque control. The proposed algorithm makes use of previously discarded states, that can increase the operational range of asymmetric converters by increasing the total number of switching states available for control. The proposed algorithm was simulated while controlling an induction machine and compared with the classical direct torque control.
